SELECTING STEEP DOWN GRADE
Tho portion of the West Shores track selected has
faat IN fha milo
experiments we're made on the down grade whtc
most marked the point at which the brakes we're 10 be
applied and the track staked on several hundrea
feet below that the distance could be the more easy
calculated train Of fifty freight cars, each 80 ieet
inches long and Of G000O pounds capacity was used TOT
the tests Where a speed OF about twenty miles per
hourwas required the train started one and half
miles up the road where the speed was to be at the rate
of forty miles, start OF miles and perhaps little
moro was given. The locomotive OF the train was No.
